In the present study, we report the design and synthesis of novel analogs of cinnamates, thiocinnamates and thionocinnamates and evaluated the potencies of these analogs to inhibit TNF-α induced ICAM-1 expression on human endothelial cells. By using whole cell-ELISA, our screening data demonstrated that ethyl 3′,4′,5′-trimethoxythionocinnamate (ETMTC) is the most potent inhibitor of TNF-α induced ICAM-1, VCAM-1 and E-selectin. As functional consequences, ETMTC abrogated TNF-α induced adhesion of neutrophils to the endothelial monolayer. Structure-activity relationship studies revealed the critical role of the chain-length of the alkyl group in the alcohol moiety, number of methoxy groups in the aromatic ring of the cinnamoyl moiety and the presence of the α, β- C-C double bond in the thiocinnamates and thionocinnamates.
